Commonly used materials for carburizing and quenching gears and 2 major aspects that need to be considered when selecting them

The commonly used materials for carburizing and quenching gears and the two major aspects that need to be considered when selecting them are as follows, for reference and understanding. For unclear parts or related requirements, you can consult EP for free.

XNUMX. Commonly used materials for carburizing and quenching gears:

1. When the gear modulus m<=6:

Choose 20CrMnTi and 20CrMnMo materials.

2, 6>=Modulus m<=12:

Choose 20rMnMo, 20CrNi2MoA materials.

3. Modulus m>=12:

Choose 20CrNi2Mo, 17CrNiMo6 materials.

2. Two aspects that need to be considered in the selection of carburizing and quenching gear materials:

1. Good carburizing performance:

Generally, alloy steels containing carbide forming elements, such as Cr-Mo steel, Cr-Mn steel, and Cr-Ni steel, are used.

2. Ensure the hardness of the gear core:

For this reason, forLarge gear, Choose Cr-Ni-Mo and other steels.

When selecting materials, it is necessary to consider factors such as material hardness, hardenability, purity, comprehensive performance and economy.

The comprehensive properties include fatigue strength, bending strength, pitting resistance, toughness, notch sensitivity and processing characteristics.
